Cicadas also often sing in chorus, which makes it more difficult for a predator to locate an individual. Cicadas are so conspicuous that many of their common names were initially given to them by children. As a result cicadas probably have the most colourful common names in Mankind is looking for food not just on this planet but on others. the insect world.

Refugial habitats, such as the riparian and rainforest along the Eprapah Creek Corridor, are areas of high biodiversity conservation value even though they may be small in area. Protecting these small hotspots of biodiversity in an otherwise dry, fire-prone landscape presents a number of challenges for local land managers. Refugia – areas facilitate the persistence of species during large-scale, long-term climatic change – are increasingly important for conservation planning. Riparian corridors often support higher biodiversity than non-riparian habitat and provide a valuable refuge for many species during droughts and fires the nature of this habitat makes it potential climate refugia. Climate refugia are those areas less likely to undergo significant climate induced changes and therefore valuable as they protect biodiversity. As climate change continues it’s expected that the koala distribution will contract East and South and it would be prudent to protect and rehabilitate the wetter habitats currently threatened by urbanisation. Eprapah currently supports many species. Research undertaken in the Eprapah Creek corridor found the following. o many invertebrates were recorded during the study, some of these not recorded previously, o surprisingly low number of introduced invertebrates were recorded, o a strong tendency of the invertebrate assemblages to vary according to vegetation type and canopy cover; and o a potential biodiversity ‘hotspot’, viz. Eprapah Creek Corridor, is flagged by the land snails. Land snails are significant indicators of both environmental health and biodiversity hotspots. The study above found 18 species belonging to 9 families, 4 species of the environmentally sensitive family Charopidae were found at the Eprapah Creek Corridor. What the study has found, given the significant land snail fauna identified, is that the Eprapah Creek corridor is a biodiversity ‘hotspot’. A hotspot is defined as habitat that contains the most important and significant habitats where threatened species of plants and animals of outstanding universal value from the point of view of science and conservation still survive. If we look at ant species along the Eprapah Creek corridor the diversity is equally impressive with 142 ant species recorded across the surveyed areas. If many species are to have a future in the Redlands and Bayside region it will be essential that refugia like the Eprapah Creek corridor are protected from development, inappropriate fire regimes and feral flora and fauna.

Plangia graminea (Serville) (Orthoptera: Tettigoniidae) is considered a minor sporadic pest in vineyards of the Western Cape Province, South Africa, and was the focus of this study. In the past few seasons (since 2012) P. graminea appeared to have caused a substantial amount of damage leading to great concern among the wine farmers of the Western Cape Province. Very little was known about the biology and ecology of this species, and no monitoring method was available for this pest. The overall aim of the present study was, therefore, to investigate the biology and ecology of P. graminea in vineyards of the Western Cape to contribute knowledge towards the formulation of a sustainable integrated pest management program, as well as to establish an appropriate monitoring system.

  • An Appraisal of the Higher Classification of Cicadas (Hemiptera: Cicadoidea) with Special Reference to the Australian Fauna
    © Copyright Australian Museum, 2005 Records of the Australian Museum (2005) Vol. 57: 375–446. ISSN 0067-1975 An Appraisal of the Higher Classification of Cicadas (Hemiptera: Cicadoidea) with Special Reference to the Australian Fauna M.S. MOULDS Australian Museum, 6 College Street, Sydney NSW 2010, Australia [email protected] ABSTRACT. The history of cicada family classification is reviewed and the current status of all previously proposed families and subfamilies summarized. All tribal rankings associated with the Australian fauna are similarly documented. A cladistic analysis of generic relationships has been used to test the validity of currently held views on family and subfamily groupings. The analysis has been based upon an exhaustive study of nymphal and adult morphology, including both external and internal adult structures, and the first comparative study of male and female internal reproductive systems is included. Only two families are justified, the Tettigarctidae and Cicadidae. The latter are here considered to comprise three subfamilies, the Cicadinae, Cicadettinae n.stat. (= Tibicininae auct.) and the Tettigadinae (encompassing the Tibicinini, Platypediidae and Tettigadidae). Of particular note is the transfer of Tibicina Amyot, the type genus of the subfamily Tibicininae, to the subfamily Tettigadinae. The subfamily Plautillinae (containing only the genus Plautilla) is now placed at tribal rank within the Cicadinae. The subtribe Ydiellaria is raised to tribal rank. The American genus Magicicada Davis, previously of the tribe Tibicinini, now falls within the Taphurini. Three new tribes are recognized within the Australian fauna, the Tamasini n.tribe to accommodate Tamasa Distant and Parnkalla Distant, Jassopsaltriini n.tribe to accommodate Jassopsaltria Ashton and Burbungini n.tribe to accommodate Burbunga Distant.

    Solid State NMR Investigation of Protein-Based Biomaterials Resilin: An Extremely Efficient Elastomeric Protein by Andrew L. C. Reddin B.Sc., Dalhousie University, 2008 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in The Faculty of Graduate Studies (Physics) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) April, 2012 © Andrew L. C. Reddin 2012 Abstract Solid state nuclear magnetic resonance experiments were performed in order to investigate the microscopic properties of three resilin/resilin-like proteins: An16, rec1-resilin, and nat- ural resilin in dragonfly tendons. Three different types of experiments were performed: measurements of chemical shifts in 13C spectra, measurements of residual quadrupole cou- plings in deuterated water absorbed in the samples, and measurements of proton residual dipole couplings based on the buildup of multiple quantum coherences. The results suggest that the molecular chains in the materials tested are primarily randomly coiled and lacking in regular structure, and are able to easily change between many transient conformations. These conformations can vary significantly in terms of their structural characteristics, re- sulting in a broad distribution of localized dynamics. When stretched, An16 showed a slightly increased tendency to adopt β-sheet secondary structure. The natural resilin also exhibited slightly more rigid structure than the other materials, which may be related to greater efficiency in the natural crosslinking process. ii Table of Contents Abstract
